Actually, I had this conversation recently. I checked a variety of
places and I couldn't find an RFC that said CNAME -> CNAME is a "must
not". In fact I found this snippet in rfc1912 which seems to imply that
it is legal:
Also, having chained records such as CNAMEs pointing to CNAMEs may
make administration issues easier, but is known to tickle bugs in
some resolvers that fail to check loops correctly. As a result some
hosts may not be able to resolve such names.
